Well, three things on that list are languages that are basically DSLs (Shell to a degree, SQL) or Markup Languages (HTML). Comparing any of those to e.g. C++, Go, Ruby or Python is like comparing apples to oranges and I don't see, how that is a useful distinction. Scala and Haskell are distinctly non-C-like. Both are functional languages with types. Maybe that is a factor. Actually, in a new project that wouldn't be "low-level" work on e.g. operating systems, drivers or high-throughput networking software I would strongly suggest using Clojure/ ClojureScript. The net productivity, onboarding speed and efficiency are great. Both are quite performant as well and integrate into the Java/JavaScript world with ease, so there are libraries and tools present. Using babashka or the Node.JS target for ClojureScript could be great for scripting as well, although Python or Hy (Clojure on top of Python basically) are strong contenders because of libraries.
